3) Apply priming paint (for painted sur-

face) evenly onto the surface where
sealing rubber is to be adhered and
where adhesive agent is to be applied
(on the cab (8)).

 Priming paint (for painted sur-

face): Sunrise MSI Primer 24

●

Do not apply primer more than twice;
otherwise, the performance of the prim-
er will be reduced.

●

Applying location: Cover the whole area
of (a). Dimension of (a): 25mm

●

Besides the above locations, apply
primer also onto the right window glass
and the cab door lower window glass.

●

Dry the primer for at least 5 minutes
(within 8 hours).

●

Do not use wrong priming paint.

If, for example, glass primer is mistak-
enly used, wash it with unleaded gaso-
line.

4) Apply priming paint (for glass surface)

onto the contact surface of window
glass (9).

 Glass primer:

Sunrise MSI Primer 35

●

Do not apply the primer more than
twice; otherwise, the performance of
the primer will be reduced.

●

Priming area: Apply the priming paint
on the contact surface of glass (9)
(rubber seal (6)adhering location) and
along cab frame (8).

●

Leave a 5 mm margin uncoated along
the black strip adjacent to the clear
area of the glass.

●

When priming paint has been coated,
dry it for at least 5 minutes (within 8
hours).

●

Do not use wrong primer.

If wrong glass primer is used, wash it
with unleaded gasoline.

rubber seal before the window glass is
installed.

●

Do not touch the cleaned area on the
glass before rubber seal is adhered.

●

Be careful not to allow the rubber seal
on the corners to peel off.

●

When sticking rubber seal (6) along the
